Just south of Mounds 24-26 is a group of four mounds-53, 28, 29, and 27. Three of these-53, 28, and 29-form a north-south line. Mound 27 is east of Mounds 28 and 29. Whether these mounds are related as a group is not known, and the details of each will be discussed separately. Patrick’s map shows Mound 27 as a conical mound with a bulge on the west side, which gives the overall mound an oval base. Mound 27 appears larger than Mound 29 but smaller than Mound 28. Moorehead makes no reference to this mound in his discussions, and he probably did not excavate into it. The Thomas Map (1894) indicates a height of 15 feet (4.6 meters), as does McAdams’ earlier map (McAdams 1882). Remnants of this mound are indicated on the UWM Map with the base at an elevation of 129 meters (423.2 feet) and a peak elevation of 129.8 meters (425.85 feet), suggesting that all that remains is a mound 0.8 meters (2.6 feet) in height. On the 1922 aerial photograph (Crook 1923:Figure 6), the area of Mound 27 shows a square-shaped patch of disturbed soil with what appears to be an elevated center. This squarish outline is especially apparent on the west, north, and south sides, while the east end appears to be more diffuse. The general oval shape indicated by Patrick suggests the possibility of weathering and reshaping of the mound by this time. The aerial photos and the way Patrick draws this mound imply that it may be a multiple-level mound similar to Mounds 10 and 11.
